Application

The Check Flap is designed to prevent backflows at sewer overflow locations as well as in retention tanks and basins. Receiving stream outlets can also be equipped with the Check Flap for flood control applications. In case of rising down-stream water levels the Check Flap will prevent water from getting into the sewer system. Overloading of sewer systems and sewage treatment plants is avoided and energy costs for pumping systems and sewage treatment are reduced.
